Abstract: Social media users’information avoidance behavior of rejecting or ignoring induced by negative social inference seriously impedes the dissemination of medical crowdfunding information. From the perspective of psychology and adopting experimental method, the paper explores the psychological mechanism and boundary conditions of negative social inference on social media users’medical crowdfunding information intention. The results suggest that negative social inference can not only directly inhibit users’medical crowdfunding information sharing intention, but also inhabit by inducing users’ social anxiety and compulsive feeling. In general, the closer the social distance, the weaker the inhibition of negative social inference; the lower the perceived information authenticity, the stronger the inhibition of negative social inference. However, social distance induces users’differentiated information processing path, which leads to the closer the social distance, the greater rather than the weaker the inhibition of negative social inference at a low perceived information authenticity. The study provides a theoretical reference for a comprehensive understanding of the psychological mechanism of negative social inference on social media users’medical crowdfunding information sharing intention, and also provides practical guidance for effective intervention in users’psychology and behavior of information sharing.
